Read the carefully the following passage and give answer the questions.

Modern living has programmed our lives to a hectic, monotonous schedule that we have forgotten the gentle smile that once fleeted across the human face. Smile has the power to dissolve all worries. It has the all-pervasive ability to lift us from the abysmal depth of gloominess. We should not be cowed down by work pressure that a constant frown imprisons our face. In built confidence and positive attitude help a smile to blossom. A face bereft of smile makes us unarmed for it is the smile that is a pleasant weapon which resists all hurdles and problems that depress us. If we learn to smile in a crisis, it shows that we have the forbearance and courage to face the crisis. A smile, after all, helps us preserve our perfect present unmindful of our past of future.
